HERMAN (l. ERIEBE, F ELU@ ISLAND, ILLINOES.

\ To allai/lam `15 may concern.'

.,...Be it known that lf, HERMAN C. Pinnen,

vrcitizen or' the United Statearesiding at Blue -.Island, in the county ,of Cool; and State of rr lllinois7 have inventeda certain new and useful improvement in Draft-Gears, of

which the following isa full, clear, concise V- andl exact description.

. component parts of thebeenynamed.

-My invention-relates to `draft vgears of the type employing inner and outer followers actuated by couplersiockers individual to, the followers and movable thereby, and.: means,- operating through said rockers, for

resisting the approach of 'the followers to ward each other.' This motion resisting means. is preferably 'in the yform of spring' mechanisim particularly'where 'friction is not relied upon to resist the relative movement or' the followers.

- lt is` the ob]eet of my inventionto improve the construction` and. arrangement of the gear which have In practising my invention l employ at least two sets of interacting rochers. each 2 set' having one rocker individual to each'A follower' and inovable-thereby. llhe rockers of'each. set interact'through a Heating roller structure, there being desirably one roller individual to each rocker. -The rollers opcrate upon and are carried `by a floating. 'member that is included in the floating roller structure 'and which separates the rollers belonging to the dilierent sets of rocker-s.` The rockers are interposed between-two motion resistingelements, each element being;f individual to a follower and in lalineinent with the' other element and with both followers. The aforesaid floating member of theiiioatiiig roller structure also ber that prevents the rockers from falling out7 which maywliappen in the event oi" breakage 'or distortion of the center sills and other parts of the under structure ofthe car. There are features respecting` vthe preferred form .of floating' member which are claimed herein irrespective of thepres- 'enceror absence of the rollers `pertaining showing the preferred embodiment then-fotA and in which Figure l' isa sectional view taken generally Online l-l of Fig. 2; F10.

Y Lilie parts are indicated by similar characters of reference throughout the diilirn ent iigures. i

The coupler 1 has a coupler shank 2 to which the outer ends of a yoke are secured in outer follower 5 is engaged b v the coupler butt 6 and ris moved inwardly whenever the coupler is subject to suliiciei'it pushingtrain. The inner follower is engaged by the inner end orV theeoupler yoke 3- and is movable outwardly when the' coupler is subject to suiiieient pulling," strain. The. extent to which the outer `follower isinovable outwardly is limited by the cuter stops 8. The extent to wliiclrthe 'incr follower 7 is movable inwardly is'liniited by the inner stops 9. All of the said stops are riveted against the center sills 10 that liorm a part oi? the underfraine structure of a car equipped with the draft gear. rlFhe followers 5 and 7 are in the nature oi' spring barrels which house the cooperating spring' elements 1l and l2 oi mechanism that is employed to resist the movement ,of l either follower toward the other and tor eiiect the return 0j the 'followers toward the stops respectively pertain y ing thereto. preferably acts as a retaining' block or inem- Une or more sets or' rockers are disposed between the followers. l have illustrated two sets of rockers, each set including a rocker 13 individual to the outer follower 5 and a rocker lfl individual to the inner 100 follower 7.

The'outer Yfollower 5 carries two seats or mountings 51, one for each rocker 13 to rock upon. The inner follower, similarly, carries two seats or Inonntings 71 one for each m5 rocker le to roclr upon. Allof the rockersare of similar construction. the rockers of each set being symmetrically, arranged. They interact preferably-by being .operated upon by the coiled springs 11, l2 of thence im@ cib tion resisting mechanism, these springs serv- .ing to oniiose the relative movement of the follower-s by opposing the attendant follower effected rocking` movement of the rock a ers. lilach rocker has a part thereof which is in engagement with the seat provided upon the follower inflivduil thereto curved to form a segment of a cylinder, the seat upon the follower engaged thereby being similarly ci'lryed. lily this construction each rocker has an axis of rotation which is substnntially lixed with respect to the follower imlividual thereto. llach rocker preferably formed with a cavity for receiving the adjacent end of the correspoiuling spring, such a cavity being illustrated at l5 in Fig. (l. The aforesaid seats 51, 71 and the recit-- ers one, r saine are desirably placed upright, in which event the follower l5 is provided with inner ledges 52 between which. the roclcers are disposed and the follower T provided with outer ledges 72 between which the rochers lll are disposed, these ledges in'eventing the rochers from moving up and down materially.

The 'floating member lli is hollow or bobo like and sui'liciently incloses maintain them in assembly with each other and other iiiortions of the gear in the event of breakage or distortion of the center sills or other parts of the under structure of the gear. Upposing portions of the rockers of the two sets project into the interior of the box-like hollow Heating member 16 which is disposed. transversely of the gear and between. the center sills for this purpose. ln order that this floating member lll may also forni a part of the floating roller structure 'l divide the floating member into two conipertinents by means of a partition 161 par ailel with the open ends of the member and es nabrir transversely of the gear. The rollers :use ilem'ably in the forni of eylin fflriral `ire li' which have fulcra fixed Elli resi ct lo the iloatirin' member lll.. the

central portions of these cylinder segments being rom fel roncenlrically with the axes flureof and conveying the corresiondingly rounded ','orneix i'oriued by the partitivfns lill' und the ui'night sides of the member ib.

The rockers of the two sets interact through the intermediation of the Heating roller `structure whereby the springs in both followers cooperate.

While I have i rein shown and particularly described the preferred embodiment of my invention l do not wish to be limted to the precisedetails of construction shown as changes may readily be made "without departing from the spirit of my invention, but having thus described my invention I claim as new and desire to secure by Letters Patent the following draft gear including a coupler; linner and outer followers actuated thereby and movable each toward the other; springs, one iudivdual to each follower, for resisting the approach of the followers toward each other; two interacting rockers, one rocker being individual to each follower and actuatable thereby, said rockers being interposed between and engaged by said springs; and a AHeating); roller structure interposed between said rockers. i
